Duplicate Parameters in Configuration File

Duplicate parameters are allowed in the configuration file, ics.conf . This can lead to some confusion about the value of the parameter. To determine which instance of a parameter is used by the system, find the last instance in the file. The system uses the value of the last instance of the parameter that it finds when processing the file.

Best practices: Add all changes to the end of the ics.conf file in a section labeled something like # My Parameter Changes. To keep a history of changes made, add a comment describing the reason for the change, and the date.

Periodically, comment out old changes that are no longer used, or if you do not care about a history of changes, delete old unused duplicates, leaving only the latest change in the file.
